Overall this addon is unusable because of this.

I'm assuming you have a "class_name State" somewhere in your code? It was conflicting with WATTest's local State Class. This is why GDScript requires namespaces.

Should be fixed by 019283a

thanks @CodeDarigan
I had not even considered this, I do have a State defined in an addon I wrote. Good to know so I can create non colliding class names & recognize this in the future.
